Plantronics Voyager 5200 - Bluetooth Headset

If you must know, I am a farmer/agricultural business owner all my life. My father and son and I all three run tractors and other farm equipment daily. We absolutely need phone earpieces that stop as much noise as possible through the microphone during calls, otherwise the customers on the other end cannot hear a word we say over the equipment noise. That was the singular reason I bought this brand earpiece. When first purchased, only 2 months ago, the Poly Voyager 5200 (along with the Poly Voyager Free 60 earbuds) worked pretty good. Only I and my father were both disappointed in the terrible fit. Impossible to make it fit at all, compared to 3 other cheap brands we'd had previously which fit quite well. Then we soon discovered that not only would they simply not fit our ears, we absolutely could not hear the other person unless there was little ambient noise. Mostly because it would not fit, or stay, in the ear. If we held it tight in the ear with one hand, not too bad. But then what is the point of an earpiece if you have to use one of your machine operating hands to babysit the thing? Next, it seemed like nobody could hear or understand a word we said. Finally, Dad and I were on a call together and WOW!!! The sound of his voice over the mic was literally like he was trying to talk through a plasic bag with the mic 10 feet away. Some words were completely missing in between. Other words came through fine. But mostly it was just garbled and muffled and very distant sounding. And sometimes absolutely no sound came through at all. He said mine sounded the same sometimes, but mine was the Poly Voyager Free 60 earbuds (I will review those pieces of garbage separately). We downloaded the app, we did everything. I had even bought him the separate charging case. Yet from the get-go this thing was TOTAL GARBAGE. A tin can and string is more dependable, and sounds much better than this thing. I paid a hundred dollars for this junk. For 3 years I had been eyeing these things, since they are the "name" brand earpieces for noise cancelling mics. Supposed to be the industry leaders in that. But I never could afford to put out that much money for earpieces. But finally, I decided to splurge and go all out. What a fool I feel myself to be. Yes, this company took us for a ride and we paid for it! I have now gone back to the Delton earpieces I had before, and they are quite decent. 10 times easier to use. Fit just fine. Keep a charge while talking all day and listening to music for at least 3 to 4 DAYS, and charge with USB-C quick chargers. And they are more affordable. So what has happened with this Poly company? Either nobody out there that uses these things actually use them, or there are a lot of fools out there. My recommendation? Look elsewhere for your earpiece. These are garbage.
